Since more and more arm chips support device tree, it'd be better add

PROC_DEVICETREE

quoted

in arch/arm/Kconfig to avoid duplicate code.

I think this should remain user choice. If its going to be selected,
then you might as well just remove the option altogether. Perhaps just
make the option default to yes.

Hmm, sounds reasonable from your point. So the better choice is to set the

option default to Y if the board has dt support just like tegra_defconfig
and at91_dt_defconfig,  right? thanks.

Regards,
Xiao
